FOREWORD

The International Organization of Legal Metrology (OIML) is a worldwide, intergovernmental organization whose primary aim is to harmonize the regulations and metrological controls applied by the national metrological services, or related organizations, of its Member States. The two main categories of OIML publications are: 1) International Recommendations (OIML R), which are model regulations that establish the metrological

characteristics required of certain measuring instruments and which specify methods and equipment for checking their conformity; the OIML Member States shall implement these Recommendations to the greatest possible extent;

2) International Documents (OIML D), which are informative in nature and intended to improve the work of the

metrological services. OIML Draft Recommendations and Documents are developed by technical committees or subcommittees which are formed by the Member States. Certain international and regional institutions also participate on a consultation basis. Cooperative agreements are established between OIML and certain institutions, such as ISO and IEC, with the objective of avoiding contradictory requirements; consequently, manufacturers and users of measuring instruments, test laboratories, etc. may apply simultaneously OIML publications and those of other institutions. International Recommendations and International Documents are published in French (F) and English (E) and are subject to periodic revision. OIML publications may be obtained from the Organization's headquarters: Bureau International de Métrologie Légale 11, rue Turgot - 75009 Paris - France Telephone: 33 (0)1 48 78 12 82 and 42 85 27 11 Fax: 33 (0)1 42 82 17 27

INTRODUCTION This "test report format" aims at presenting, in a standardized format, the results of the various tests and examinations to which a type of a totalizing automatic weighing instrument shall be submitted with a view to its approval. The test report format consists of two parts, a "checklist" and the "test report" itself. The checklist is a summary of the examinations carried out on the instrument. It includes the conclusions of the results of the test performed, experimental or visual checks based on the requirements of Part 1. The words or condensed sentences aim at reminding the examiner of the requirements in OIML R 107-1 without reproducing them. The test report is a record of the results of the tests carried out on the instrument. The "test report" forms have been produced based on the tests detailed in OIML R 107-1. All metrology services or laboratories evaluating types of totalizing automatic weighing instruments accordingly to R 107 or to national or regional regulations based on this OIML Recommendation are strongly advised to use this test report format, directly or after translation into a language other than English or French. Its direct use in English or in French, or in both languages, is even more strongly recommended whenever test results may be transmitted by the country performing these tests to the approving authorities of another country, under bi- or multilateral cooperation agreements. In the framework of the OIML Certificate System for measuring instruments, use of this test report format is mandatory. The "information concerning the test equipment used for type evaluation" shall cover all test equipment which has been used in determining the test results given in a report. The information may be a short list containing only essential data (name, type, reference number for purpose of traceability). For example: - Verification standards (accuracy, or accuracy class, and No.) - Simulator for testing of modules (name, type, traceability and No.) - Climatic test and static temperature chamber (name, type and No.) - Electrical tests, bursts (name of the instrument, type and No.) - Description of the procedure of field calibration for the test of immunity to radiated electromagnetic fields Note concerning the numbering of the following pages In addition to a sequential numbering: "R 107-2 page .." at the bottom of the pages of this publication, a special place is left at the top of each page (starting with the following page) for numbering the pages of reports established following this model; in particular, some tests (e.g. metrological performance tests) shall be repeated several times, each test being reported individually on a separate page following the relevant format; in the same way, a multiple range instrument shall be tested separately for each range and a separate form (including the general information form) shall be filled out for each range. For a given report, it is advisable to complete the sequential numbering of each page by the indication of the total number of pages of the report.

8 EXAMINATION OF THE CONSTRUCTION OF THE INSTRUMENT Use this page to indicate any description or information pertaining to the instrument, additional to that already contained in this report and in the accompanying national type approval or OIML certificate. This may include a picture of the complete instrument, a description of its main components, and any remark which could be useful for authorities responsible for the initial or subsequent verifications of individual instruments built according to the type. It may also include references to the manufacturer description. Description: Remarks:


R107-2 Page 73 of 83

9 CHECKLIST The checklist has been developed based on the following principles: To include requirements that cannot be tested according to the type evaluation tests 1 to 8 in the summary of evaluation above, but shall be checked visually, e.g. the descriptive markings (3.9); To include requirements which indicate prohibitions of some functions, e.g. semi-automatic zero-setting devices shall not be operable during automatic operation (3.8.1.4); Not to include general requirements, e.g. suitability for use (3.1); This checklist is intended to serve as a summary of the results of examinations to be performed and not as a procedure. The items on this checklist are provided to recall the requirements specified in R 107-1 and they shall not be considered as a substitution for these requirements. The requirements that are not included in this type evaluation report (tests 1 to 8 and checklist 9) are considered to be globally covered by the type approval or OIML certificate (e.g. classification criteria [2.2 and 2.3], suitability for use [3.1]). For non-mandatory devices, the checklist provides space to indicate whether or not the device exists and, if appropriate, its type. A cross in the box for “present” indicates that the device exists and that it complies with the definition given in the terminology; when indicating that a device is “not present”, also check the boxes to indicate that the tests are not applicable (see p. 5). If appropriate, the results stated in this checklist may be supplemented by remarks given on additional pages.
